ToaZZ'who'm-z't maybo n, v- V Be it'knoivn at I, FRANK MORTON, a

citizen of the 1 United States, residing at' VMuskogee, in the county of Muskogee and State ofOkl'ahoma, have invented new and useful Improvements in Ventilating Storage Bins, ofwhich the-followingfis aspecificafer the grain from one point toanother at intervals as is the ordinary practice.

It is well lniown that the storage of grain has always been with risks and moreor less loss, owing to the'tendency'of the grain to heat while in the bins. ',The' ordinary grain from" one bin to another at certain intervals of time whereby to effect ventilation, but this method has several disadvantages the principal one of which is that transferring does not properly cool the grain and another of which is the chipping of the grain which always causes considerable loss.

Unless the grain is ventilated by some means it will naturally eventually deteriorate so as to be rendered useless for food purposes. Grain in this unventilated condition also develops weevils and this is .another source of great loss. The ordinary method of transferring the grain from bin to bin requires the expenditure of a great amount of time and labor and is an expen sive operation as it requires the services of workmen and involves a great deal of wear and tear on the necessary machinery together with the expense ofthe fuel for driving the machinery. Furthermore such transfer involves the giving off of vasit' clouds of dust which are very deleterious to the healthof the workmen employed in and around the elevator. This is known as mill dust and frequently causes explosions and spontaneous combustion. Furthermore empty bins must; always be reserved so as to be available for purposes of transfer as will be of course understood. It is with the above mentioned objects and conditions in view that the present invention has been designed.

The essential-object of the present invention is the provision of a bin of novel constrnction and with which is associated a suitable blower whereby larger quantities of] 7 air under pressure may be forced through the entire bin for'fthe purpose of removing.

cooling as well the foul air therein and drying the grain.

;'An additional object is theprovision of a b1n of this character .which will be' simple;

and inexpensive in constructiom; highly efficient muse, durable -1n service and a material improvement.- W1l3lf.'tl1e above and other that and ,7

advantages in View, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying f'drawings in which Figure 1 is a longitudinal sectional View through a bin" constructedaccordance .withimy invention. method oftreatment-His by transferringthe Figure 2 is a crosssectionalj view therethr'oi'igh showing the rectangular top.

Figure 3 is a cross section-al view of .a

modified form showing a circular or cylindrical top.

Referring more particularly to the draw-- ings I have shown the bin 10 as having a lower or outer hopper-shaped bottom 11 provided centrally with an opening 12 for the discharge-of grain, this opening being nor' mally closed by the usual sliding gate 13.

Secured-within the bin in parallel relation and above the bottom 11 is a hopper-shaped member or false bottom 14 which is likewise formed at its center with a discharge open-- ing 15 which is never closed. filled with grain every spacewithin thebin is occupied with grain except the space between the lower bottom 11 and the upper .95

bottom 14. This space extending'all around the bin is a spacious air chamber 16 into- As the bin is which the grain never enters and with which 7 it does not interfere. a I

Entering into'this air chamber 16 at some point near the top is a pipe 17 through which air is forced from any'suitable blower 18 which may be driven by any preferred means. c c In Figures 1 and 2 I haveshown the bin as being rectangular in cross section while in Figure 3 I have shown it as being circular in cross section and it will be understood that the shape makes no difference whatever. I

Assuming that the bin is full of grain,

it is merely necessary to operate the blower 18 whereupon air will be forced under pressure into the space 16 and through the open ing 15 up into and through all the grain in the bin. It is Well known that grain in a bin is not a compact body and that there is a small space between all of the individual kernels which will readily permit such air under pressure to pass through the entire mass so that every kernel will be subjected to the action of the air for the purpose of effecting cooling and drying so that in this way the entire contents of the bin may be kept in a thoroughly satisfactory condition which will insure keeping of the grain for a long period of time.

ple construction which may be very read-V ily ventilated and which will insure the saving not only of grain but also expenditure of time and money as well as labor in the proper treatment of the grain.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having described the invention I claim 1. A bin comprising an elongated hollow body arranged in upright position and having a hopper-like bottom provided with a normally closed discharge opening, a false bottom within the lower portion of the body spaced from the hopper-like bottom to define a continuous air space said false 'bottom being formed with an opening of greater size than the discharge opening at the bottom of the body, and means for forcing compressed air into said continuous air space. Y I

2. A bin comprising an upright hollow body, a hopper-shaped bottom therefor having a normally closed outlet opening, a false bottom located above and in spaced parallel relation to said first namedbottom and like- 7 wise formed with a discharge opening registering with said'first named opening, a

pipe leading through said first named bot- 7 tom near one outer edge thereof and communicating wit-h the space between the two bottoms, and means for forcing air under pressure through said pipe.

In testimony whereof I affix my signature.

FRANK MORTON.
